HVAC Certification and Licensing: Everything You Need to Know
If you’re planning to launch or advance a career in heating, ventilation, and air conditioning (HVAC), certification and licensing are critical. This guide covers the requirements, costs, timelines, and best paths to get certified and licensed as an HVAC professional in 2025.
What Is HVAC Certification?
HVAC certification proves that you have the training and skills to safely install, repair, and maintain heating and cooling systems. The most common is the federally required EPA 608 certification, but other certifications exist from NATE, HVAC Excellence, and trade schools.
Why Do You Need an HVAC License?
Most states require an HVAC license to legally perform HVAC work. A license can help you:
- Stay compliant with state laws
- Qualify for higher-paying contracts
- Build trust with customers
Federal vs. State Certification
